My invention yrelates to vending machines andn'iore particularly tomachines for vending flat articles such Las newspapers, yperiodicals,etc. l

An object ,of the vinvention is to provide a coin controlled mechanismhaving `a slidable drawer ior singly delivering the articles which isonly permitted to be withdrawn to deliver articles after arequisitenumber of'V coins have been deposited into the machine. lFurther-the invention provides a nor1nally latched coin controlledv'drawer which `is permitted to be withdrawn .step by step to fullideliveryposition.upon singly depositing awnumber ofcoins into themachine. Y l'V-th the preceding and other `objects and advantages 1inmind, the invention consists iin-'the'novel combination of elements,constructions .and 'arrangement of yparts to be hereinafter speciicallyreferred to, claimed and illustrated in the accompanying drawings,wherein: Figure 1 is a perspective ofthe machine,

rectangular cabinet 5 having a hinged lid 6 is provided and is adapted.to be mounted on a vertical post 8 by means of ybrackets Y9 secured vtothe rear wall thereof, and which are secured to the post byl aconventional lock 10. V i

In order vto vsingly deliver vknewspapers vor other analogous :articlesplaced in the vcabinet, a channel shaped drawer 11 =is slidably mountedupon 'the .bottom wall ofthecabinet and is yadapted 'to bewithdrawnthererom through a slot 12.feXt'ending the Sentire length ofthe yfront wall'of the cabinet. Aspartic'ularly illustrated in `Figure'10, onek .of i

the side flanges of the drawer is slid'ablein an inverted L-shaped guide13 mounted 'upon the bottom wall of the cabinetat pone side thereof. Tolimit *the withdrawal .of ithe drawera :pair of v,parallel rods 14 aresecured tothe lower ends :of plates 15 `attached to `the'front wallofthe drawer andy projecting below the same. -These'rods w14. arelongitudinally movable ina rectangular chamber v'16 provided on the'underface of the rbottom of fthe cabinet and lext-ending the entirelength thereof. Attached to these rods is La cross head 17 ywhichcontacts with 'the Jfront vwall of the cabinet when the drawer. is infull withdrawn position. In addition to :the cross head limitingtheoutward movement of the drawer, it serves to guidetheV drawer in `atrue horizontal Vdirectionfsofthat it will readily pass through theslotf12.

For thel purpose of separating the lower-v vmostna'rticle 4'contained inthe cabinet, -a

normally horizontally disposed :plate 18 is hinged tothe upper face ofthe drawer at one end thereof as indicated at 19. This plate ismaintained `in `spaced relation to .the drawer :by means of adown-turned flange 2O 'formed on lthe free end of the plate `and anglebrackets '21 formed on the forward longitudinal edge thereof; The rea-rlongitudinal. edge ofthe plate is bevelled as 11522 to facilitatopassing of the `plate between the bottom article and 4the one next inorder .so

that the bottom Varticle will lie upon the drawer .each time it is movedinto Ithe cabinet.

55 .Referring 'to the invention y.in detail ya ill'ustrated in Fig. .11the plate iis formed with av rearwardly extending eXtension 15 vprovidedwith a hinge pin 16a which is received in a slotted braclret 17a securedto the drawer 11. To compensate for newspapers of various thicknesses,adjusting screws'18a pass through theopposite ends of the plate 18 andare adjustable against the drawer 11 to regulate the height of thisplate.

A coin controlled mechanism is provided for controlling the withdrawalof the drawer. j This mechanism `comprises a channel shaped member 23extending along one of the end walls of the cabinet and adjacentV edgeof the drawer. As illustrated in Figure 8, ythe channel shaped member isformed with a coin receiving Yopening 24 in one face and an angularlydisposed lip or guide 25 below the same. As illustrated in Figure 7 thecoin opening 24 registers with an inclined slot 26 in the adjacent sideVnettthrough which theV shank passes.

wall of the cabinet which merges into a circular coin entrance opening27 at its upper eind.` A coin ejector 28 is movable longitudinally inthe channel shaped member and is Vnormally urged towards the forward endthereof by means of a flexible element 29 trained over, pulleys 3G andconnected to a contractile spring 31, the latter being secured to therear wall of the cabinet at its upper end.` A shank 32 projectslaterallyfrom the coin ejector and is movable in a' longitudinal slot 33 formedin one side of thel channel shaped member and communicating with theopening 24. The slot 33 isv in Vregistration with a longitudinal slot 34formed in thev adjacent end wall of the cab handleko vis carried by theouter end of the shank whereby the ejector is slid rearwardly in thechannel shaped member. Asl particularly illustrated in-Figure 4, thechannel shaped member is provided with notches 36 which are successivelyengaged by the lateral `end 37 of a pivoted latch 38 carried by thedrawer adjacent its rear end. This latch is normally retained in aposition to engage one of the notches by means of an expansible spring39 interposed between the drawer and rear end of the latch. To acili- Ytate movementot the lateral end 37 outV of the notches, one of the sidewalls of each is bevelled, as at 40.`

` Arranged above the channel shaped member isa horizontal bar 41 havingpairs of oppositely bevelled recesses 42 in its under face. The bar 41is supported from a vertical cleat 48v'attached to one ofV the sidewalls of the cabinet and a horizontally disposed cleat 44 secured-to thebottom wall of the cabinet behind the drawer. Ank upstanding finger45'is pivotally supported on a horizontal pivot pin 46 passingtransversely through a rectangular casing 47. This casing 47 is attachedto the drawer directly below the bar 41 so that the nger 45 normallyprojects into an opening 48 provided in the bar adjacent its rear end.The linger 45 is normally retained in an angular position by'coilsprings 48 bearing against the finger at opposite sides and anchored ina bloclrY 49 held within the casing below the pivot pin 46. It will beobserved that as the drawer is withdrawn the finger rides on the underface ot the bar and successively engages one notch ofeach pair, thusmaking it impossible to partially withdraw the drawer and then push itto normal position.

Reversely, kthe finger successively engages the other notch of each pairwhen they drawer 1s being returned to normal position.Y It

will therefore be seen that it is necessary to complete the movement ofthe drawer when it is started in either direction.

A coin box 50 is provided rearwardly of the compartment 16 and hascommunication with. the channel shaped member 23 by way of an opening 51formed in the bottom of the cabinet.

In order to observe the contents of theY cabinet, a glass or window 52is arranged in the front wall of the cabinet.

In theoperation of the invention the purchaser rst places a coin in theopening 27 the extension 37 of the latch element rides on the upper edgeof the channel shaped member until it reaches the neXt notch 86:

At this time the extension moves kinto this notch to prevent the furtheroutward movement of the drawer. A second coin is now deposited and theejector again actuated as above stated to disengage the latch elementand permit Vthe drawer to be fully withdrawn.

When the drawer has been with-V drawn the plate 18 is swung upwardlyas.l Y

illustrated in Figure 11 to permit the paperL or other article to .beremoved. Y'
